Item Open Access Evaluating Applied Theatre Using Amateur Community Actors as a Modality for Pedestrian Education Among Primary School Students in Moshi, Tanzania(2014) Dideriksen, ChrissyBackground: The WHO estimates that in 2010 there were over 10,000 road traffic injury related fatalities in Tanzania. Pedestrians accounted for a third of those fatalities. Education is essential to improving Tanzanians' road safety. Theatre has been used as a modality for education for many years, though most efficacy research focuses on professionally created and delivered theatre. The act of creating theatre is an inherently collaborative process, making it a good tool for participatory interventions that involve community members. Collaborative, theatre-based interventions have several benefits for global health projects: 1) they are relatively low-cost; 2) they incorporate community ideas encouraging stakeholder investment; and 3) they have potential to be self sustaining after development aid has stepped away. However, there are two main impediments to using collaborative theatre in global health interventions. First, there is little investigation on the efficacy of collaborative theatre to educate. Second, there are few guidelines to help drama-based programs take advantage of collaboration with amateur community members for health topics.
This study combined qualitative and quantitative methods to understand how participatory theatre with amateur community participants can convey health topics such as road and pedestrian safety in Tanzania. The study measured local primary students' pedestrian knowledge, evaluated theatrical performance as a method to teach pedestrian safety, and explored how community members could use drama techniques to become advocates for road traffic injury prevention. This project sought to adapt a replicable framework of applied theatre exercises to address health issues in a collaborative manner between community members and educators.
Hypothesis: Participatory theatre will increase pedestrian knowledge among primary students.
Methods: Young adult volunteers from Moshi, Tanzania participated in a month long workshop to create a performance to teach road and pedestrian safety. The workshop process was evaluated through qualitative methods, including journaling by the workshop facilitator, daily informal group discussions, and performance response cards from community leaders. At the end of the project, 17 open-ended surveys were administered in Kiswahili among the participants. A focus group with 8 participants was also conducted at the end of the project. A follow up focus group was conducted four months following the end of the project.
Workshop participants presented their play in Kiswahili to local primary schools. Knowledge assessment surveys were administered in Kiswahili to 439 primary school students. Pre and post knowledge assessment surveys were utilized to measure the impact that the community created play had on students' pedestrian knowledge.
Results: Primary school audiences showed statistical improvement between their pre and post survey scores. The average mean score improved from 71.40% of the pedestrian knowledge items correctly answered to 84.39% (P>
Item Open Access Viewpoint Adaptation for Person DetectionWang, P; Collins, L; Morton, K; Torrione, PAn object detector performs suboptimally when applied to image data taken from a viewpoint different from the one with which it was trained. In this paper, we present a viewpoint adaptation algo- rithm that allows a trained single-view person detector to be adapted to a new, distinct viewpoint. We first illustrate how a feature space trans- formation can be inferred from a known homography between the source and target viewpoints. Second, we show that a variety of trained clas- sifiers can be modified to behave as if that transformation were applied to each testing instance. The proposed algorithm is evaluated on a new synthetic multi-view dataset as well as images from the PETS 2007 and CAVIAR datasets, yielding substantial performance improvements when adapting single-view person detectors to new viewpoints while increas- ing the detector frame rate. This work has the potential to improve person detection performance for cameras at non-standard viewpoints while simplifying data collection and feature extraction
